What is the next number in the series: 10, 50, 250, 1250, ...?
Answer:
6250
The pattern consists of multiplying each term by 5 to reach the next term (10 x 5 = 50, 50 x 5 = 250). Applying this multiplier to 1250 yields 6250.
2422
Identify the next term in the sequence: 6, 24, 96, 384, ...
Answer:
1536
This is a geometric series where every term is generated by multiplying the previous term by 4 (6 x 4 = 24). Continuing this pattern, 384 x 4 gives 1536.
2423
Which number completes the series: 7, 14, 28, 56, ...?
Answer:
112
In this sequence, each number is precisely double the previous number (7 x 2 = 14, 14 x 2 = 28). To find the next number, we multiply 56 by 2, resulting in 112.
2424
Find the next number in the series: 2, 6, 18, 54, ...
Answer:
162
This geometric progression has a common multiplier of 3. Checking the terms: 2 x 3 = 6, and 6 x 3 = 18. Following this established rule, 54 x 3 equals 162.
2425
What number comes next: 4, 16, 64, 256, ...?
Answer:
1024
This sequence is generated by multiplying the preceding number by 4 to obtain the next term (4 x 4 = 16, 16 x 4 = 64). Multiplying 256 by 4 gives the correct answer, 1024.
2426
Identify the missing number: 5, 25, 125, 625, ...
Answer:
3125
The pattern follows a geometric series where each number is multiplied by 5 (5 x 5 = 25, 25 x 5 = 125). Multiplying 625 by 5 yields the next term, 3125.
2427
What is the next term in the sequence: 3, 9, 27, 81, ...?
Answer:
243
This series represents consecutive powers of 3 (3^1, 3^2, 3^3, 3^4), or simply multiplying each term by 3. The next logical term is 81 x 3, which equals 243.
2428
Find the next number in the geometric series: 2, 4, 8, 16, ...
Answer:
32
This is a geometric progression where each term is multiplied by a constant factor of 2 to get the next term (2 x 2 = 4, 4 x 2 = 8). Multiplying the last term 16 by 2 gives 32.
2429
What comes next in the sequence: 81, 72, 63, 54, ...?
Answer:
45
These numbers are decreasing multiples of 9, which means the common difference is -9 (81 - 9 = 72). By subtracting 9 from the final term 54, we obtain the next number, 45.
2430
Find the missing term: 50, 44, 38, 32, ...
Answer:
26
This sequence features a constant decrease of 6 between terms (50 - 6 = 44). To extend the series, subtract 6 from the last given number: 32 - 6 equals 26.
